The vulnerability CVE-2025-53283 affects the borisolhor Drop Uploader for CF7 - Drag&Drop File Uploader Addon up to version 2.4.1. It allows an attacker to upload files of dangerous types without restriction, including web shells, which can be executed on the server. This results in complete compromise of the affected system, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H). The vulnerability is publicly known as of November 6, 2025, but no patch or official fix has been documented in the provided data.

Successful exploitation allows remote attackers to upload and execute arbitrary code on the web server, leading to full system compromise including complete loss of confidentiality, integrity, and availability. This can result in unauthorized access, data theft, data modification, and denial of service.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict or disable the vulnerable file upload functionality if possible. Implement additional security controls such as web application firewalls to detect and block malicious file uploads. Monitor for suspicious activity related to file uploads.
